HELP!, Screen shutting off for weird reasons

could be the monitor failing, any chance of borrowing another or using a tv to test with?

There isn't much in the way of software glitches i can think of that would behave this way but possibly maybe hardware. I can go through a list if you like and see if anything can be done.

1) Video drivers up to date?
2) Video card seated properly in the PCIe slot?
3) Hertz settings set to the right setting in monitor properties?
4) Connections between computer and monitor properly connected?
5) Screen might have buildup of dust inside and maybe overheating, if that's possible.

Very strange issue, sounds like the Monitor could be losing signal by the slightest vibration as you move around the desk doing various tasks. Could try give it a slight bump to replicate any issues.

I would try another monitor or tv if you can to make sure.

Well the monitor is brand new, an Acer s230HL, and since I'm able to temporarily stop this issue with system restore, that kinda rules out a monitor problem. So its likely software... I'll check all my drivers first I guess

Search for Power Options on Search, and switch to High Performance, rather than the recommended "Balanced" or "Power Saver"
On the left, you have a tab, saying "Choose when to Turn of Display". Change both of the Entries to "Never".

Cheers,

Trust me, I've tried all that already too, my power management is set to balanced, but my screen is set to shut off in 10 minutes, but that's not the problem.

Like I said in my first post, its triggered by certain actions, like plugging in my PSP to usb, or disabling/enabling my wireless adapter.

I'm wondering if maybe its some sort of virus designed to piss people off... XD

Could be some power options linked to your USB ports. Did you check advanced power options? (Like when you go to your "Balanced" settings, there's another menu after that called "Change Advanced Power Options" I'd look at every options under there). Also check for the drivers of your wireless adapter in Device Manager, I think there could be other power options in there too linked to the device itself.

I checked all those options, all seems good.

I'll have to wait until it starts doing it again, since I've used system restore, its stopped for now. Once it starts again I'll give more details on what triggers it.
